TimeRemaining—Wolfram Documentation

gives the number of seconds remaining until the earliest enclosing TimeConstrained will request the current computation to stop.

Details

If constrained by several nested TimeConstrained wrappers, TimeRemaining[] returns the time to the earliest time constraint.
Without an enclosing TimeConstrained, TimeRemaining[] returns Infinity.
TimeRemaining is accurate only down to a granularity of at least $TimeUnit seconds.
TimeRemaining is based on absolute real time, not just CPU time.
